The video of Harrison Ford playing Uncharted 3 last week was clearly meant to communicate some kind of blessing from Indiana Jones to Nathan Drake. And Indy's a professor who taught lessons with his fists. This video features Naughty Dog's Robert Cogburn talking about how you can do the same in the studio's hotly anticipated threequel. Even though Dr. Jones didn't fire off quite as many rounds as Nathan Drake does, I think he'd approve.
